COLLAR-BUTTON.

Specification of Letters Patent.

Patented March 17, 1908.

Application led. September 19, 1956. Serial No. 336.191.

To all whom it may concern: I

Be it known that I, DAVID A. HART, a citizen of the United States, residing at Attleboro, in the county of Bristol and State of Massachusetts, 'have invented an Im )rovement in Collar-Buttons, of which 'the ollow ing description, in connection' with thc ac companying drawings, is a'speoifcation, like letters on the drawings representin 'like parts. My invention is a com osite col ar button, having for its object theimprovements relating to increased strength, neatness and du- A rability.

lprovide a back, preferably of ornamental material, such pearl, and a post, preferably of spunor drawn metal, held to the Back4 by a prong-fastener, thereby securing the parts innnovably, said back preferably having undercut recesses at its front and back for receiving the opposite metal portions and locking the parts immovably.

My invention will be further explained and the novel features thereof pointed out more at length in the course of the 'following description made with reference to the accompanying drawings, in which I have illustrated a'preferred embodiment of my invention.

In the drawings, Figure 1 is a central vertical sectional view of my improved collar button partially put together; Fig. 2 shows the same completein side elevation; Fig. 3 is a view'in side elevation of the post and its securing means; Fig. l is a plan View of the back; Fig. 5 is a bottom view of the button before the covering cap is put on; Fig. 6 is a transverse sectional view ol' said cap; and4 Fig. 7 isI an enlarged detail in cross section of the lower portion` of the completebutton.

My button comprises a back 1 and a post 2 and preferably also a cap 3, which, aside from the novel features for securing them together which constitute my invention, may be of any approved or preferred shape ma.- terial and construction. As herein shown the post 2 is of spun or drawn metal, having a usual enlargement or head. Li at its outer end and a narro \\f-neck portion 5 terminating in a ilaring shouldered base .6. The back 1 is herein, indicated as pearl, bone or other substance requiring considerable relative thick ness, although I do not intend to restrict myself to any particular material.. Throu h this back 1 I bore holes 7 to correspond to t ie number of tangs or prongs 8 Which extend integrally from the post 2, three thereof being herein shown. In the particularsembodiment oi' my invention contained in the drawings these holes are located adjacent the rim of the back 1. at vthe'periphery of a broad, shallow, flat-bottomed recess 9 pro- 50 vided at the rear sideef said back, and the tangs or prongs E extend from the cxtreme 'edge or rim of the flared base 6 of the post 2. This gives an extremely strong construction. The recess 9 hasundercut walls as indicated at l0, and referably also the back 1 has a similar un ercut recess 11 on its front face. The depressions in the back which. constitute the recesses 9 and 11 have coextensive areas, the latter te receivel and retain the Haring shouldered ibase 6 of the post 2, and the former toeenceal the bent-over ends of the tangs or prongs 8 and toreceive and retain the can v In assembling the button the prongs S of the post are inserted from the front face through the holes of the back and simultaneously the shouldered base 6 is pressed forcibl downward into the recess 11 by a suitab e machine provided for the purpose until the extreme rim or edge of the flared shouldered base is forced outwardly and unyieldingly into the undercut periphery of the recess 11. Thereupon the projecting ends of the prongs 8 are clenched or bent over inwardly toward each other, es shown in Fig. 5, whereupon the cap 3 is inserted in the rear recess 9, a drop ofsolder 12 being preferably placed'at the 'unctionor lapped ends of the prongs 8 an d tllen said cap is pressed forcibly inwardly until its edges are forced tightly into immovable engagement with the undercut edges 10 of the recess 9.

The above construction is smooth at all oints, exceedingly strong, cannot Work l)oose, the button is uiclily put together, and 1s inexpensive. appearance as none of the fastenings are visible. In case 'a larger or a smaller number of prongs is employed, the size of the' capri-nay be correspondingly varied and in the cheaper varictles it may be altogetherl omitted, although it adds to the strength and especially to the neatncss of the appearance. relative. thickness of the back may be varieda and the depth for example, ofv the recesses,

'espcciell the rear recess 9 may be varied,

so tha ecap 3 may be set in so deeply that it cannot come in contact with the wearer. no

TheV ila-red basecoperatcs with the interlocked prong or prongs in giving strong t is neat in external i It will also be understood that the/'105 bracing effects, so thatthere is no liability of breaking the collar button. The cap also serves, irrespective of the solder, to hold the prongs down flat, and presents a neat, smooth external appearance.

As already intimated, it will be understood that many changes in form, arrangement and construction of parts may be resorted to without departing from the spirit and scope of my patent and invention.

Having described my invention, what l claim as new and desire to secure by Letters Patent is, f

l. An article of manufacture, consisting of a collar button, having a transversely perforated back containing a recess in its front sideto iit and retain the shouldered base of the post, combined With a long slender post terminating at one end in a head, and at its opposite end in a flaring shouldered base pro-v vided With a thin, flexible, integral prong extending transversely through said perforated back, bent into clamping engagement with the under side of the bach and permanently secured thereto, said head, post, and ,back

being irremovably fastened solidly together- 2. An article of manufacture, consisting of --a collar button, having a post terminating at its outer end in a head and at its inner end in a shouldered base provided with prongs, a back provided. with transverse holes and with an undercut recess at its rear side, said post having its shouldered base restin tightly against the front side of said baci with its prongs extending through said transverse holes and bent into said recess against .the rear side of the back, and a cap fitting tightly against, and beneath' the undercut Walls of said recess, and maintaining. the parts of the entire collar button at all times relatively firm and immovable.
